Hi,
Need some help to locate
Low power (up to 80 uA Quiescent current ) 4 Channel OP AMP (TSSOP 14) .
Supply Voltage 2.7 < V+ (Rail to Rail output voltage) to use as Buffer
Thanks a lot.

Hello Yonatan,
There are a several devices from the Precision Amplifier portfolio we can recommend that may meet your needs. Here are a few highlights:
TLV2404 if you want the lowest possible quiescent current (0.88 µA per channel).
OPA4330 if low offset is also a priority (Max Vos = 50 µV).
OPA4317 if you need additional bandwidth (1 MHz at G=1).
OPA4244 if a wider supply range is necessary (2.2 < Vs < 36).
If you want to explore all TI Precision Amplifiers that meet your design needs (20 devices) please see the following custom parametric search link:
Please let us know if you have any additional questions or have additional selection criteria we can utilize to find you the best possible part for your application.

Hello Yonatan,
I am assuming the 80uA is for all four amplifiers (20uA max per amplifier) in a "PW' (TSSOP-14) package:
GPN | VosRoomMax (mV) | IsMaxCh (mA) | GbwTyp (MHz) | 1kPrice ($) |
LMP2234 | 0.15 | 0.009 | 0.13 | 1.86 |
LPV324-N | 7 | 0.01 | 0.152 | 0.48 |
OPA4379 | 1.5 | 0.0055 | 0.09 | 0.8 |
TLC27L4 | 10 | 0.017 | 0.085 | 0.42 |
TLV2244 | 3 | 0.00125 | 0.0055 | 1.57 |
TLV2324 | 10 | 0.017 | 0.085 | 1.46 |
TLV2404 | 1.2 | 0.00095 | 0.0055 | 1.91 |
Beware that microamp level Iq devices have difficulty driving loads less than 100k - so be mindful of max sink/source currents if using for a buffer.
